- My invention relates to anew and useful improvement'in' afurnace adapted for use for heating purposes, andparticularly a furnace for generating steam crime with which a hot 5 water heating system may-,beused. It, isaan object of the present invention to providefa furnace of this kind in which the maximum area of heating surface may be exposed to the heated gases, 'andthe efficiency 7 10 'ofthe furnace raised togahigh degree,

It is another obj ectofthe present invention to provide a furnacenofthis kind formed from 7 t lurality of sectionswhich may'beeasily and quickly assembled.

i 15,} 1 "Another ob ect. of the invention istheprovision of a plurality 'ofinterlocking sections iwhich,-when assembled, provide baflied pas- 2 sagesfor the heatedgases, thusretarding'the gases in their passage from the combustion chamber to-the flue, and insuring" a maximum combustion.

. Another object of the invention is=the protvision ofa furnaceiof this class which" will 'be'easilyand'quickly a'ssfembled,and economicaliof manufacture. j f v :Other objects will appear hereinafter.

:;The'invention consists in' the combination and arrangement .of parts hereinafter described and claimdpii L hich form a in-which, 1518 a partifoffthis specification, and

i 'Figy r is asectional ,view i takengon line wo l lihas, at-it's' upper edge, aninwardly turned "The invention 'bef best'understood by l ai-r eference to the; accompanying drawings flange 14:, providing theopening 15 to afford communication'between the ash pit positioned therebelow, and the combustion chamber po sitioned thereaboves Projecting upwardly from the flange 14 at the forwardside thereof is a bead16 adapted to engage in a groove 17 formed in the section which is positioned thereabove. This section, as shown inFig.

2, comprises outer walls 18 and 19 which projectfupwardly from a base,the base resting ontheinturned flange 14. Positioned below the'fiange'l and in alignment with the open- ,ing 15isa grate 20. As shown in Fig.2, an

opening is provided in the lowermost section, this opening being closed by the door 21 which is mountedon the frame 22, this frame being secured to the section. An air vent 23 is formed in the door 2'1. Positioned inwardly of the inner wall 19and formed integral with the inner wall 19 is a globe shapedmember 24 which forms a chamber in communication with the space between the'walls 18 and 19 through the-necks'2'5. 1 rojecting upwardly from the upper surface of the globe shaped member 24, centrally thereof, is a' neck 26 which isinteriorly threaded for thereception of anipple 27. A superimposed section comprising an outerwall 28 is adapted for mountng onv the, lowermost section. A plurality of these superimposed sections are used, each section posltlonedabove being constructed "identical with the section positioned beneath,

at 28' to provide a tubular extension projecting outwardlyffrom the normal position of the outer surface of thewall 28, and this tubular extension is provided with a base 29 having an opening formed therein registering with an opening formed in the 'top'30 of the lowermost section, these openings being interiorly threadedfor'the reception of a nipple 31 which serves to'bind these sections together; As shown in ,Fig. 3 there are provided three of these tubular bulged formed members, although the number'may be va- I claim as new and desire to secure by Letters Patent is:

A furnace of the classdescribed comprisd I ing a plurality of duplicate double walled secti0ns,'with the spaces between said walls inintercommunication, the inner wall of eachlof said sections being bulged inwardly I away from the outer wall, a plurality of centrally disposed, disk-like hollow intercomr e rnunicating sections enclosed by said doublef walled sections, the edges of adjacent disc like; sections extending in overlapping, spaced relation to; said bulged walls, the space between said bulged walls and disklike sections forming sinuous pasages for the escapeof gas, asupporting section comprising'spaced walls forming continuations of I Y the walls of the double walled sections, the space between said walls being in communigoication with the space between said double walled sections, a centrally disposed hollow globe-shaped'member connected to said sup- 7 porting section and disk-like members, and

establishing communicationbetween the enclosed spaces of said sections and members,

and providing support for said disk-like members, a hollowtop section communicating with said double walled sections and said disk-like sections and having an exit flue in V 1 communication with said sinuous'passage's,

' said supporting section inclosing a combustion chamber space. I I V InLtestimony whereof I have signed the foregoing,"
